Regular dental checkups at least twice per year are important to maintain good dental health and catch any issues early. During a checkup, the dentist will examine your teeth, take your medical history, and provide cleanings to remove plaque that is difficult to reach with brushing alone. They can also recommend treatments like polishing and fluoride to further protect teeth. Any dental problems, like toothaches or cracks, should be addressed promptly with a dentist to prevent further damage or pain.
